Final answer:
The correct type of coupling described for use with pipes with grooves near the end is a flanged split coupling. It is bolted together with a gasket for sealing and allows for easy maintenance.option d is correct.
Step-by-step explanation:
The correct answer to the question is D) Flanged. A flanged split coupling is designed for use with pipes that have grooves near their ends. The flange refers to a rim, collar, or disc that is provided for strength or for attachment to another object, as the flange on the end of a pipe
. In the context of piping systems, flanged couplings are typically bolted together with a gasket in between for sealing. This allows for an easy connection and disconnection for maintenance or system reconfiguration. Despite other types of couplings existing, like the compression, expansion, and plain-end couplings, the description in this question particularly matches that of the flanged type.
